Spur gear module 4 z=14 with hub hardened

Product Description

Spur gear module 4, z=14, with hub, hardened

The module 4 spur gear z=14 with hub is a precision gear transmission component designed to transmit high torques at a constant ratio. The teeth are induction hardened to 45-55 HRC, which significantly increases wear resistance and extends gear service life in heavily loaded transmissions.

Technical data

Frequently asked questions

How do you calculate the ratio of a gear pair of two module gears with different numbers of teeth?

The ratio is calculated as the quotient of the number of teeth of the driven gear to that of the driving gear (i = Z2/Z1); the module must be identical for both gears, otherwise meshing will not work at all.

How do you cut a keyway in a module gear with a small hub?

In gears with a small hub, the keyway is slotted with great care so as not to weaken the wall above the tooth. If there is not enough space, we recommend dispensing with a standard key (feather key) in favour of mounting with clamping bushes (locking assemblies).

What is backlash and why does it matter?

It is a small gap between mating teeth, necessary for lubrication and thermal tolerance; too little backlash leads to seizing and overheating, while too much leads to jerking and faster tooth wear.

How should gears be stored correctly before installation?

Preferably in a dry room, protected against moisture and dust, with a light layer of preservative oil on the teeth and bore - especially important for C45E carbon steel, which can start to corrode without protection.

Where is this product used?

It performs well in power transmission systems in machine tools, production lines and sliding gates, where it works together with a gear rack of the same module.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
